Primary Assay — Desert Locust
Collision Avoidance (LGMD/DCMD)
Schistocerca gregaria
Looming stimuli reliably evoke escape jumps gated by the LGMD-DCMD pathway. Response latency, jump direction, and threshold to a defined looming velocity profile quantify the circuit.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Schistocerca gregaria.
| Parameter | Unit | Description |
|---|---|---|
| Response latency | ms | Stimulus onset to motor response |
| Jump direction | deg | Heading away from looming |
| Looming threshold | l/v ratio | Critical visual angle/speed |
| Spike rate (DCMD) | spikes/s | Neural readout if recording |
